so was modeling some models in maya and now i'm trying to import them to zbrush for detail. But i have a few problems here.

-First one is, that some of the faces are not visible (which means that i have to fix the normals on those faces right?). What would be the best way to go about doing that?

-Second one in zbrush is more of a warning, that my model contains non-standard polygons and gives me 2 options to fix them.

-The third one is saying that i have unused 3D points.

Somewhere between here, while zbrush trys to fix this, the model gets deformed. I'm not sure which fix does it because zbrush changes the geometry and delets points.

Now the model has holes and strange verts connected.

What does one have to look for, when modeling and knowing that he's going to use zbrush. Because i noticed, even if i extrude a simple box in the "wrong" way, the faces aren't visible in zbrush. So if you HAVE to push the extruded face "inside", you have to change the normals on all of those new faces for zbrush to see them?

Hope you can help, had trouble finding anything about the second and definetly the third problems on the web.

ya, your normals are reversed. but if you want to see both sides of meshes in ZBrush, turn on the amazingly ambiguously named "Double" setting in the Tool palette/Display Properties rollout.

that's not a problem really.

never seen that. try poly cleanup in Maya. You must have some pretty shaggy topology.

I suggest you toggle normals in Maya to check which way things are facing while you extrude. I made a toolbox that has a lot of little "good topology" scripts that you might find useful for modelling:
